I'm nearly finished changing my diff ratio to 3.7 and just wondering if anyone knows the part number for the speedo gears to suit 3.7? I currently have the 32:12 speedo gears which suit the 4.1 diff ratio but I know the 80 series also came out as 3.7 diff ratio in certain countries/models so I'm assuming there should be a different set of speedo gears to match right? I already have the transfer apart to fix up a couple oil leaks so was just hoping to swap out the gears now while it's all apart instead of having to wire up and purchase one of those electronic speedo correction boxes.
